Goal of the System• Provide Value to the Customer
• Integrate into Intwine’s “Triple-Play Service” (Cellular ISP, Voice, IoTmonitoring)
• Reduce customer’s energy bill:• Peak demand reduction• Time-shifting of energy consumption (if time-of-use prices)
• Facilitate integration of DER• Solar integration (with net metering or feed-in tariffs)• Battery Energy Storage (to increase amount of load shaping)

Goal of the System• Provide Value to the Utility/Aggregator
• Increase hosting capacity of Solar• Prevent reverse flow of power during peak-solar• Flatten the load-curve to reduce ramping requirements in evening
• Single aggregation point to reduce complexity for managing DER• Enable power import/export constraints• Demand Response platform

Neighborhood Coordination• Not every building is equivalent• Resources can be ‘shared’
• Further improves PV hosting capacity
• Enables decentralized “campus” level optimization

Next Steps• Challenges:
• Diversity of loads/equipment• Diversity of customer behavior
• Looking for partners for 100 home/building pilot• Starting projects with universities to explore campus-level approach
